Its melting point is 28.7 C, and it boils at 690 C. The electronic configuration of Cesium is (Xe)(6s 1). Its atomic radius is 0.267 nm. At room temperature Cesium has a body-centered cubic crystal ...

The definition of the hyperfine transitions of cesium was — by international agreement — 9,192,631,770 Hz. A 5 MHz crystal oscillator generates a signal that is modulated by a 137 Hz signal.

Scientists developed a highly accurate optical ion clock, improving time measurement precision by 1,000 times.

The focus of the study was a bulk single crystal of a topological kagome metal ... arranged on a so-called kagome lattice—a pattern of interlaced triangles and hexagons—stacked on top of one another, ...

Researchers at the University of California San Diego have been able to explain how adding small amounts of cesium or rubidium ... which have a three-part crystal structure composed of three ...

In an optical atomic clock, atoms are irradiated with laser light. If the laser has exactly the right frequency, the atoms change their quantum mechanical state. All external influences on the atoms ...

The next generation of atomic clocks "ticks" with the frequency of a laser. This is about 100,000 times faster than the microwave frequencies of the cesium clocks which are generating the second at ...

Furthermore, understanding the laser-induced damage thresholds (LIDT) of nonlinear optical crystals like β-barium borate (BBO) and cesium lithium borate (CLBO) is essential for optimizing their ...
